Went to Costa Adeje [CA] a couple of years ago
I was pleasantly surprised with what was available
The usual place for action is Playa De America which is [relatively] a tip for Tenerife
CA isn't as obvious for opportunities for our fave sport, no strip clubs etc
However there are some R&T venues, advertised on the interweb easy to find, a thai place & a few others
Do some research before you leave
These are in the roads heading back from Fanabe beach, the thai gaff is about in the middle
Towards the end of the beach where MickeyDs is there are a couple, maybe a couple of hundred metres from the beach
There's a row of crappy tourist shops on two levels, you need to head to the 1st floor
Two like right next to each other, heading away from the beach on the right hand side of the road
I went to both, they stand out a mile
IIRC more of a tantric feel to the 1st place when you get to the 1st floor
Futon on the floor, thankfully the burd knew the square root of FA about tantric & it was full on
The next door / two doors down the massage was on a bench tho i did see a strategically place hole in the middle
The tantric type gaff / burd was better
I've had another look on goggle & some more places have opened up
The biggest challenge will be getting away from the family & hiding a punting mobile on a trip is risky at best
I'd add their number to your main phone & call em on WA
Save as an obscure contact then block after the session, tho from my dealings with both venues neither got in touch afterwards
Good luck, enjoy & report back
